A method and an associated SDCDN device for delivering data content in a communication network. A software defined content delivery network (SDCDN) monitors one or more performance indicators regarding an exchange of the data content between a first content delivery network (CDN) and at least one client device using a communication channel, The SDCDN determines that at least one performance indicator of the one or more performance indicators exceeds a threshold performance value. The SDCDN identifies a different CDN in operative communication with the at least one client device. The different CDN includes the data content. In response to determining that at least one performance indicatorexceeds the threshold performance value, the SDCDN transmits a transfer command to the at least one client device to cause the at least one client device to switch to the different CDN and receive the data content from the different CDN.

Software defined content delivery network for flexible, real-time management of large-scale data transfers

A bidirectional connection between a multimedia stream distribution system and a user is used to communicate operational data to and from the user. The bidirectional connection is separate from a multimedia connection that transfers a multimedia stream from the multimedia stream distribution system to the user. Providing a bidirectional connection separate from the multimedia connection is advantageous, among other reasons, because the operational data can be collected effectively at the multimedia stream distribution system independent of any limitations in the multimedia connection. To organize users and reduce processing load, the multimedia stream distribution system assigns users to user groups based on shared characteristics. Groups may be used to propagate information to the users as well as analyze information collected from the users in an efficient manner.
